  • Radial neodymium motor structure.
  • Vented cast aluminium chassis for improved thermal control of voice coil.
  • Forced air cooling vented voice coil gap.
  • Aluminium demodulation ring.
  • 3" High temperature CCAW voice coil.
  • Rear aluminium heat sink.

 

The PD.103NR1 is intended for use as a high power mid range driver in multiway systems. The optimised radial neodymium motor system allows more efficient management of the magnetic flux. Forced air venting and rear aluminium base plate keeps the motor temperature under control and reduces power compression to a minimum. The unit features a 3-inch, high temperature, CCAW voice coil capable of handling 550W (AES). The PD.103NR1 exhibits an average sensitivity of 100dB across its working band and will produce an SPL of 126 dB in a 15Ltr sealed enclosure.
